“…In large‐scale high gain planar A‐PAA, a few thousand of active antenna elements are employed to provide the required high gain level and to satisfy a certain side lobe level. In practical applications, the antenna array aperture could be one printed circuit board (PCB) standalone panel or divided into two or more separate panels which are still complex and expensive. However, for cost‐effective and less design complexity, smaller active sub‐arrays (modules) with small dimensions, such as 4 × 4 can be used to implement large‐scale A‐PAA aperture in any size (scalable).…”

“…All the RF signals from all the modules are distributed/combined by power splitter/combiner which is integrated at the back‐plane as shown in Figure . Traditionally, power splitters/combiners based metallic planar lines or metallic rectangular waveguide (RWG) are used to split/combine the RF‐power to these modules. However, they are lossy, bulky, or expensive at mm‐wave band.…”

In this article, efficient integration approach of building large‐scale active‐phased array antenna (A‐PAA) for millimeter‐wave (mm‐wave) is presented. In this approach, large‐scale A‐PAA is constructed from smaller size A‐PAAs (modules) with inter‐element spacing of half‐wave length and assembled into efficient planar waveguide feeding platform based on substrate integrated waveguide (SIW) technology. Simple low profile vertical RF‐connection between the SIW splitter/combiner outputs and the modules using surface mount super‐mini board‐to‐board (SM‐SMC) is presented. Embedded metallic via‐pad transition integrated into the SIW board is employed to match the SM‐SMC to the SIW mode at Ka band. Sixteen‐way power splitter with transitions to SM‐SMCs is designed at 30 GHz. The measured results of S‐parameters show insertion loss of <0.70 dB over the operating frequencies 28.50‐30.50 GHz.

Free space (also termed quasi‐optical) metasurfaces have recently been designed and proposed as new types of polarizers that allow polarization control of an impinging wave in ways that are not possible with conventional designs. However, existing methods for tunable metasurface polarizers are not able to fully control the polarization dynamically; additionally, at mm‐wave and submillimeter bands, they typically suffer from high losses, which are predominantly produced by the inherent limitations of the tuning elements or materials. An electromechanically tunable reﬂection polariser that has the ability to fully control the polarization of an impinging wave has been designed, fabricated, and experimentally tested in a frequency band centered at 57 GHz. The proposed technique utilizes a variable air cavity between a periodic metasurface array and a ground plane, controlled by a piezoelectric actuator. The periodic metasurface element consists of two slightly different cross‐shaped metallic elements arranged in a periodic triangular lattice. Full‐wave simulations are presented and experimentally validated with measurements. The proposed approach is scalable from microwave up to THz frequencies with low‐loss performance due to the nature of the tuning technology whereby the tuning element is not interfering with the electromagnetic waves in the structure.
